Specication of Letters Patent.

Patented Jan. 27, 1920.

Application led January 17, 1913. Serial No. 742,567.

To'aill 'whom t may concern:

' Be it'known that I, BENJAMIN S. Mo-

CLELLAN, a citizen of the United State-s, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Windows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein had to the accompanying drawings, an to the letters of reference marked thereon, which form a part of `this specication.

-This invention relates to an improved construction in windows having sliding sashes and embracing parts in the nature of weather strips adapted for maintaining tight joints between the sides of the frame and the side edges of the sash,'while permitting free movement of the sash relatively to theframe. y

My invention is more particularly designed for, and applicable to, the windows of passenger cars or coaches, but the.y features constituting the invention are equally applicable to windows used for other purl poses.

The lnventlon conslsts 1n the matters hereinaffter described and pointed out in the ap ended claims.

n' the accompanying drawings illustrating my invention-'- Figure 1 is a view in side elevation of a art of the side or jamb4 of the window rame and of the upright part or side member of a sash which engages the frame;

2 is a plan section taken on line 2-2 of Fig. 1;

Fig. 3 is a vertical section taken upon line 3 3 of Fig. 2;

Fig. 4 is a vertical section .taken upon line 4-4 of Fig.V 2;

Figs. 5 and 6 are plan sections showing different forms of construction in the resilient pressing device on the sash. Y

As shownpin said drawing, the side member or jamb of the window frame includes a wooden vertical member 5 having applied'l to its exposed face a flat metal plate 6. Secured against the plate 6 are two metal strips 7 and 8 constituting outer and inner guides or stops, and forming with 'the plate 6 a guide-groove to receive the outer edge of the upright side member 9A of the window sash. The metal strip 7, forming the outer stop, is provided with a base iiange 7 a, which extends at right angles to the body of the strip and is secured against the plate 6 by means of screws 7b or other suitable fastening means. The strip 8, forming the inner strlp, is shown 'as consisting of a piece of sheet metal bent into U-shape, as illustrated, and provided with a iiat base portion 8* whlch rests against the plate 6 of the up right frame member 5 and terminates at its inner edge in an outwardly extending folded part 8", which forms with the stop portion 8, a groove for another sash. The U-shaped stop forming portion 8 is shown as secured to the frame by means of screws 8 inserted therethrough vand through the plate 6 into the wood backing 5 of the framef The construction illustrated in the frame, by which the guide groove for the sash is formed by metal plates and strips, is such as will be used in metal car construction, wherein the exposed parts of the frame are formed of sheet metal.

Attached to the outer face ofthe upright` 1 adjacent to its side margin which engages the frame, with a longitudinally extending recess or rabbet 11, located beneath the strip 10.and adapted to receive the stop'strip 7;

v this construction enabling the strip 10 to be made of a flat piece of sheet metal, arranged in the plane of the side of the sash member to which it is secured.

Referring now to the form of construction 'shown in Figs. 1 to 4, a resilient or elastic pressing member 12 is secured to the marginal part of the sash' member 9 in positionv to press outwardly against and have sliding engagement with the inner face of the stop member 7. The elastic pressing member thus arranged, servesto press or hold the strip 10 against the outer face of said stop member; both the strip 10 and said resilient member 12 being adapted for sliding contact with the sto member 7 when the sash is moved relativey to the frame. As shown in said Figs. 1 to 4, the resilient member 12 has the form of a curved metal spring, seated in a recess formed in the rabbeted part 11 of the sash member 9. Said spring is arranged with its convex side in bearing contact with the said stop strip 7, while its ends are loosely connected with the sash in a manner permitting its central part to bend or iex inwardly. As illustrated, the spring 12 is mounted in a casing 13, of channel or U-shape, which is secured in a recess formed in the rabbeted marginal part of the sash member 9 and said casing is provided with ltwo transverse metal studs or pins 13a, against which the ends of the spring member rest or bear. The ends of said spring are bent to form inwardly curved parts 12a, 12a'adapted for engagement with the said studs 13, 13, in a manner to prevent the spring from becoming detached or falling out of the said casing.

- In the operation of the device, as clearly shown in Figs. 1 to 4, the spring member 12 presses constantly against the inner face of the stop strip 7, and by' its pressure on said Istop strip tends to shlft or move the body of the sashmember 9 in a direction away from the stop member and to draw or press the strip 10 of said sash member into close bearing or contact with the outer face of said st'op member 7. A tight joint will thus be always maintained between the stop strip 7 and the strip 10, while at the same time the pressure exerted by the spring member 12, by which the strips 7 and 10 are held in contact with each other, would not be so great as to revent the sash from being easily moved 1n raising or lowering the same. The

stop strip 7 and strip 10 on the sash, coacting in the manner described with the spring 12, serve in the nature of weather strips to maintain always a tlght joint between the v side of the sash and side of the frame, while atv the same ting serving to prevent any shaking or rattling ofthesash.-

In Fig. 5 I have shown a modified form of construction in a resilient or spring member on the sash, adapted to constitute a pressing` means acting on the inner face of the stop member. In this instance the resilient pressing means consists of a longil strips 15 and 16 in place, consists of screws,

-one of which is indicated by 16, inserted through the saidy -strips and into the sash member 9, the metal strip 16 being countersunk to receive the head of the screw, and having a hole therein for the screw, larger in diameter than the screw, so that the head of the screw will constitute a stop to limit the outward movement of the metal strip 16, while said strip will be yieldingly supported by the rubber strip 15 and will be pressed by the action of the latter against the said stop strip 7.

In Fig. 6 I have shown still another form of construction in the resilient pressing member of the sash. In this instance, a strip 17 of felt, plush or other compressible and elastic or yielding fabric is inserted in a longitudinal groove 17a formed in the outer face of the rabbeted part of the sash. The said strip 17 is made of such thickness as to press or bear against the inner face of the stop member 7, with the same results as hereinbefore described in connec tion with the other forms of resilient pressing devices illustrated.

In connection with both of the forms of pressing devices shown in Figs. 5 and 6, it 1s to be understood that the same may extend either the entire length of the sash vmember 9 or only Aa -part of the length of the same, and in connection with the pressing devices shown in Figs. V1 to 4, it will be understood that the sash member 9 may be provided with either one, or a plurality of, such pressing devices.

It it to be understood that a device embodying the features of my invention hereinbefore described, may be varied in its details from the form of such devices illus- -trated in the accompanying drawings, and I `do not, therefore, desire to be limited to the specific features of construction and design illustrated, except so far as the same may be set forth in the appended claims as consituting parts of my invention.

I claim as m'y invetnion: 1. The combination with a window frame and sash, of a metallic stop strip on the frame, a metal strip on the sash arranged in overlapping relation with the stop strip on the frame, and resilient pressing means on the sash having sliding engagement with the stop strip and actin on said stop strip in a direction to press t e strip on the sash seated in the rabbeted part of the sash and.

in a direction to acting on the sto str1 Ihe sa li yieldingly against press the strip on t s the said stop strip.

3. In a device of the class described a; my invention I aHiX my signature in the Weather stop on a Window frame, a mempresence of two Witnesses, this ith day of ber on the sash overlapping said stop, and January, A. D. 1913.
